I am running Vegas Pro 14 on Windows 7 Pro [EDIT: Win 10], x64. I am missing the option to playback video on an external monitor (see attached image). This used to work, but I do not know why it disappeared.
Under Preview Device Prefs, in the Device dropdown menu, my two display monitors do not appear (?). The only device options are something called "AJA Video Device" and "Blackmagic Design Decklink" but those are not my devices.
How can I select either of my display monitors to playback full screen video? By "full screen" I mean fill the entire display.
